Objective To study the mechanism of different forms of ST-segment elevation in acute myocardial infarction(AMI),and to investigate the distribution of its traditional Chinese medicine (TCM)syndrome types.Methods Two hundred and twelve hospitalized AMI patients with ST-segment elevation from March of 2015 to July of 2017 were divided into group A and group B.Group A had 102 cases with the elevation of concavity of STsegment,and group B had 110 cases with the elevation of arch of ST-segment.The correlation of ST-segment elevation in different forms with TCM syndrome types was analyzed.Results (1) Patients of group B were usually male,young and middle-aged,with or without short-term medical history of coronary heart disease,and coronary angiography results indicated the stenosis or occlusion of the vessels without collateral circulation.Patients in group A were usually female,aged,with medical history of coronary heart disease,and coronary angiography results indicated the existence of collateral circulation.(2) Group A was dominated by Qi-deficiency and blood-stasis syndrome,and the frequency of its syndrome types was in decreasing sequence:Qi-deficiency and blood-stasis syndrome,Qi-yin deficiency syndrome,heat-toxicity and blood-stasis syndrome,phlegm blended with bloodstasis syndrome,syndrome of cold stagnation in heart vessels.Group B was dominated by heat-toxicity and bloodstasis syndrome,and the frequency of its syndrome types was in decreasing sequence:heat-toxicity and bloodstasis syndrome,Qi-deficiency and blood-stasis syndrome,Qi-yin deficiency syndrome,syndrome of cold stagnation in heart vessels,phlegm blended with blood-stasis syndrome.The difference of the distribution of syndrome types was significant between the two groups (P ＜ 0.01).(3) In respect of the differentiation of deficiency and excess syndromes,group A was dominated by deficiency interweaved with excess syndrome,while group B was dominated by excess syndrome.The difference of the distribution of deficiency and excess syndrome was significant between the two groups (P ＜ 0.01).Conclusion AMI patients with different forms of ST-segment elevation have different TCM syndrome types.The investigation results will provide a new vision for the clinical trial of AMI treated with Chinese medicine integrated with western medicine,and will supply evidence for the syndrome differentiation and treatment of AMI patients with different forms of ST-segment elevation,which will contribute to enhancing clinical efficacy,saving life and improving prognosis.

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.

Objective To evaluate the accuracy of auditory evoked potential index (AAI) in monitoring the anesthetic depth during isoflurane anesthesia.Methods Thirty ASA Ⅰ or Ⅱ patients aged 18-55 years and undergoing elective surgery under general anesthesia were enrolled in this study. The patients were unpremedicated. Anesthesia was induced with midazolam 0.05 mg/kg, fentanyl 3 μg/kg and propofol 1 mg/kg. Tracheal intubation was facilitated with recuronium 0.1 mg/kg. The patients were mechanically ventilated (VT:40 mm Hg. Anesthesia was maintained with isoflurane inhalation and intermittent intravenous boluses of vecuronium. Isoflurane was started with high-flow (FGF, 3 L/min) for 12 min followed by low-flow (LGF, 0.5 L/min). The inspired isoflurane concentration was set at 3%. The electrocardiogram (ECG), mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2), end-tidal isoflurane concentration and AAI were continuously monitored during anesthesia and recorded before induction of anesthesia (baseline, To ), immediately after induction (T1), immediately before isoflurane inhalation (T2), at 3 min(T3), 6 min (T4), 9 min (T5) and 12 min (T6) during high-flow wash-in and at the end-tidal isoflurane concentrations of 0.8 MAC (T7), 1.0 MAC (T8) and 1.3 MAC (T9) during low-flow inhalation of isoflurane, respectively.Results AAI decreased gradually while the end-tidal isoflurane concentration increased during high-flow wash-in. And AAI was negatively correlated with the end-tidal isoflurane concentrations ( r = -0.896, P ＜ 0.01 ) during low-flow inhalation of isoflurane anesthesia.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.

Purpose To investigate the diagnostic value of dual energy CT spectrum curve combined with CT morphology in central lymph node metastasis of papillary thyroid carcinoma (PTC).Materials and Methods Thirty-one PTC patients who accepted dual energy CT double-phase enhanced scan before surgery were analyzed.Central lymph nodes with short diameter ＞ 5 mm were labelled using axial plus 3D positioning.Preoperative labelled lymph nodes were collected and marked during operation.The CT morphology of metastatic lymph nodes was analyzed.The spectrum curve slope (K) difference between metastatic and non-metastatic lymph nodes of arterial-phase and venous-phase primary lesion was compared.The critical K value and the diagnostic efficacy of K value combined with morphology were obtained according to receiver operating characteristic (ROC) curve.Results A total of 73 central lymph nodes were obtained from 31 patients,among which 51 were metastatic and 22 were non-metastatic.There was no significant difference in K value between metastatic and non-metastatic lymph nodes of arterial phase group (P＞0.05).While,there was a significant difference in K value between metastatic and non-metastatic lymph nodes of venous phase group (P＜0.05).For venous phase,the sensitivity and specificity of the K value in diagnosing central lymph node metastasis were 62.7％ and 59.1％,respectively,and combined with morphology,the sensitivity and specificity reached 76.5％ and 81.8％,respectively.Conclusion The K value of CT spectrum curve is of certain significance in predicting PTC central lymph node metastasis,and the K value combined with CT morphology can improve the accuracy of diagnosis.

Objective To investigate the clinical characteristics of hospital infection and the pathogen type,distribution and drug resistance,in the intensive care unit of our hospital,to direct proper antibiotics use and supply the scientific basis for hospital infection control. Methods The clinical data of 392 inpatients in our intensive care unit from April 2008 to March 2010 were monitored prospectively and analyzed retrospectively. Results Of the 392 impatients,78 cases had hospital infection (19.89% 78/392),112 time-case infection (28.57% 112/392). The most common infection was the main respiratory tract infections accounted for 54.46% (61/112) ,followed by urinary tract infections accounted for 15. 19% ( 17/112 ), blood infection accounted for 11.61% (13/112). 152strains pathogens were identified in the study,in which G- bacilli accounted for 69.7%, G+ bacteria accounted for 17. 8% and fungi accounted for 12.5%. Main pathogens such as acinetobacter baumannii ,pseudomonas aeruginosa,klebsiella pneumoniae, staphylococcus aureus showed multiple drug resistance in different degrees. Conclusions Intensive care unit has a high nosocomial infection rate,lower respiratory tract infection is the most frequent type and the main pathogens have different degrees of multi-drug resistance. Standardized, rational use of antibiotics,prevention of the multi-drug resistant bacteria spread may help to reduce the occurrence of hospital infection in intensive care unit.

Objective To assess the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist on prostate epithelial cells in vitro.Methods The expression of peroxisome proliferator-activated receptor γ(PPARγ) was studied by immunocytochemistry and immunofluorescence study.The RWPE-1 human prostate epithelial cell line was treated with PPARγ agonist rosiglitazone 100 μmol/L for 48 h.Analysis of apoptosis was performed by Caspase 3/7 activity assay.Mitochondria depolarization was measured by using the potential-sensitive color,JC-1.The expression of apoptosis-related proteins-Bax was investigated by immunohistochemistry.Results PPARγ mainly located in nucleus and perinucleus.RWPE-1 cell line treated with PPARγ agonist rosiglitazone showed higher Caspase 3/7 activity (10636±1032 RLU) than in control (5936±620 RLU),P＜0.01 and significantly upregulated Bax level (8250±694 vs.6017±563)than in control group,P＜0.01.In addition,mitochondrial membrane potential was depolarized in rosiglitazone treated cells.Conclusions PPARmay play important roles in the pathophysiology of BPH.The mechanism might be that PPARγ regulates cell apoptosis.It is suggested that the mitochondrial and Bax pathway might be involved in signaling PPARγ induced cell apoptosis.
